Now, if \(Z_T \ne 0\)  as suggested in [1]} we cannot solve the equation for \(T\)  as it is not algebraic anymore. We have a model with two unconstrained coupled superfields \(X, T\) . This is a simplified version of the model studied in [1]} in their eqs. (3.1), (3.2), where we can take \( \tilde{\zeta }=0, \tilde{\gamma }=0\)  to get from eq. (REF )
\(K= X {\bar{X}} + T {\bar{T}} \ , \qquad W= f X + {1\over 2 \sqrt{Z_T} } T X^2 \ .\)
